DUMPING-CAR.

SPECIFICATION forming part of Letters Patent No. 433,073, dated July 29,1890.

Application filed August 6, 1888. Serial No. 282,042. (No model.)

T all whom it may concern:

Be it known that I, GEORGE W. Dickinson, a citizen of the United Statesof America, residing at Butte, in the county of Silver Bow and Territoryof Montana, have invented certain new and useful Improvements inDumping-Cars, of which the following is a specification, reference beinghad therein to the accompanying drawings.

My invention relates to improvements in hopper-cars and cars thatdischarge their own load, used for hauling or handling ore, gravel,

y broken stone, and all material of a like character. Greatinconvenience has been experienced from the ordinary side-dump carswhere used for transporting ore, coal, dre., mainly due to the complexnature of the apparatus used in dumping them-such as chains, levers,gear-wheels, dief-not able to withstand the rough usage to which cars inthis service are subject to. It is necessary that cars for this serviceshould be of simple design and of substantial construction.

The objects of my invention are, Iirst, to provide a side-chutehopper-car of improved eonstructioinfroni which the contents or load isdischarged from the same by gravity; second, to furnish a car withinclines and its side doors with simple and substantial fastenings. Iattain these objects by the arrangement,

construction, and combination of parts, as

illustrated in the accompanying drawings, in whieh Figure l is a plan ofa car constructed in accordance with my invention. One half shows theframing of the same, and one half shows the floored inelines. Fig. 2represents the same, partly in side elevation and partly in verticallongitudinal section. Fig. 3 is a side elevation showing the side-chutedoors, with hinges, latches, ttc., for the saine. Fig. d is a verticalcross-section showing the sidechute inclines and the manner in whichthey are constructed. Fig. 5 is an end elevation of the car, Fig. G is afront viewof the latchbar detached from the car. Fig. 7 is a side viewof one of the door-props for holding a door open at such times as may berequired. Fig. 8 is a side View of a wrench for operating thedoor-latches. p

Similar letters of reference refer to similar parts throughout theseveral views.

D are transverse or distance sills framed to the side sills A and centersills B.

D is a distance-block framed to the center sills B.

The car-frame is to be tied near the distance-sills D by cross-rods.Auxiliary sills E are framed to the distance-sills D and to the endsills O.

The body-bolster, draw-timbers, draw-bars, tbc., may be attached to thecar in the ordinary manner. I

The car has three transverse or needlebeams, a center one G, and one Gnearer each end of the car. The distance the needle-beams are placedapart will be governed by the wheel-base of the truck and the distancethe body-bolster is placed from the end of the car. Side planks Il aresecured to side stakes I and I', placed directly on top 0f the side sillA, ilush with the outside face thereof and secured to the same withbolts and rods. The center stakes I are secured to the side sillon theinside of side plank lI and braced to the car-frame by the brace-rod I2.The side stakes I are secured to the side sill on the outside of sideplanks. Il is a running-board secured between the side stakes I on eachside of the car, to extend the full length of the side planks ll andsecured to the side sill A with brackets.

At each end of the car there is an incline J, extending from the top ofthe side planks H to the lower line of the ear-sills A and B. Theinclined floor-timbers J are framed at their lower end to theneedle-beam G, and also rest upon the distance-sills D. The upper end ofthe Hoor-timbers J are carried by a frame K, which is secured to thecar-sills A, B, and E with rods and bolts. A ridgepiece L extendslongitudinally through the center of the car to the outside of the endinclined frames K, and rests upon three saddleblocks L', which arefastened to the center sills B, and the ridge-piece L is fastened to thesaddle-blocks L. The side-incline chute O consists of two corner-posts Oand one center post o, framed to the needle-beams G and G at the upperend and to the side floor-sill IOO length of the side chute and aresecured ontop of the needle-beams G and G. The whole construction issupported and fastened to the car by the strap N, which is fastened tothe side-chute frame and side sill of the car. The

A side inclines O extend from the longitudinal ridge-piece L at thecenter of the car to the outside face of the side inclined floor-sill M.The end inclines J and side inclines O are covered with flooring ofsuitable thickness. When the cars are designated for transportingmaterial of a moist and adhering natu-re, the flooring on the inclinesmay be covered with sheet iron or steel,put on in plates of a suitablesize and shape to suit the size and angle of the inclines.

v The openings of the side chutes O, from which the contents of the carare discharged, are provided with doors P, made to swing outward, andhinged to side sill of the car by the hinge-straps p, p', and p2, andthe hingerod Q. In accordance with my invention the doors are to besecured, when closed, by a latch or catch near each end and also by acenter fastener.

R are latches pivoted on wrought-iron pins fr, and supported by thepivot castings 7", which are secured to the side-chute braces. Theside-chute braces and posts are slotted to receive the latches R.

R is a latch-bar bolted on the outside face of the door. The latch-barR' has av slot or notch 'r2 cut in its upper edge near each end, intowhich the latches R drop when the doors are closed.

S is a latch-shaft resting in the bearings S', which are bolted to orotherwise secured to the side sill A. The latch-shaft S is squared ateach end to receive the wrench s' by which the latches R are operated.

s are arms fastened to the latch-shaft S directly over the latches R.

T are latch-connecting rods, one end of which is attached to the arms sand t and the opposite end to the latches R and t'. Each end of thelatch-shaft S is squared to receive the wrench s', by which the latchesR are operated, as hereinafter described.

The center fastening is made by the pin U, secured on the lower side ofthe inclined chute-frame, projecting through the hole p3 posts, (one toeach door,) and the door-holder bar V' is pivoted to the casting V.holder bar V' is formedl with an offset or shoulder at c. When the doorsare closed, the holder-bai-V rests over the latch-bar R', so that whenthe doors are opened the holderbar V' is carried along with said doorsfar enough to allow the shoulder o in the holderbar V' to drop over theupper edge of the latch-bar R', thereby forming a brace which holds thedoor open.

When the cars are loaded with ore, coal, broken stone, or any vmaterialof a heavy nature, the weight of the same against the doors issufficient (the latches being released) to force them open a sufficientdistance for the door-holder bar to catch automatically and hold thedoor open, thereby keeping the weight of the door off the material thatis heing unloaded, and thus allowing all of same to get out of the car.

When the cars are loaded with sawdust, charcoal, or any material of alight character, and the weight of the same is not sufficient to forcethe doors open after the latches and fastenings are released, the crooks2, formed on the end of thc wrench s', is placed over The doorv thelatch-bar R' near either end and the doors pulled open far enough toallow the shoulder t in the holder-bar V' to drop over the upper edge ofthe latch-bar R', thus holding the doors open until the car is unloaded.

To open` the side-chute doors, first, the center fastening is to bereleased by removing the key U' from the pin U, and, second, to removethe latches R out of the notches 'r2 in the ends of the latch-bar R. Thewrench s' is placed on the squared end of the latch-shaft S, and byturning the same upward the arms s are lifted, and being connected tothe latches R by the latch-connecting rods T also lifts the latches outof the notches r2 in the latch-bar R', allowing the door to swingoutward.

Having now fully described my invention, I claim- 1. In a dumping-carhaving a ridge-piece and ltwo lateral discharge-openings and doorstherefor, the combination of the latch-bar R', the center hinge-strapp2, and the pin U, with the key U', forming a center fastening, andhorizontal latches R, engaging with the top edge o-f the latch-bar,substantially as and for thc purpose described.

2. The door-holder pivot-casting V and the door-holder bar V', incombination with the latch-bar R', whereby the door is kept open,substantially as and the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.
